Waterproof Deck Membranes FAQ

Question 1

What types of waterproof deck membranes do you install?

Accepted Answer

We install various membrane systems including liquid-applied polyurethane, modified bitumen, EPDM rubber, TPO, &specialized deck coating systems. Selection depends on substrate type, traffic requirements, climate conditions, &architectural considerations. Each system offers specific benefits for different applications.

Question 2

How long do waterproof deck membranes last?

Accepted Answer

Quality waterproof membrane systems typically last 10-25 years depending on material type, installation quality, maintenance, &environmental exposure. Liquid polyurethane systems often provide 15-20 years, while premium modified bitumen systems can exceed 20 years with proper maintenance.

Question 3

Can waterproof membranes be installed over existing surfaces?

Accepted Answer

Yes, many membrane systems can be installed over existing surfaces provided they are properly prepared. We assess existing conditions including structural integrity, drainage, &surface contamination. Some applications may require overlay preparation or selective removal for optimal adhesion and performance.

Question 4

What drainage considerations are important for deck waterproofing?

Accepted Answer

Proper drainage is critical for membrane longevity. We evaluate existing drainage systems, install additional drains if needed, ensure proper slopes (minimum 1/4 inch per foot), &integrate membrane systems with drain connections. Standing water significantly reduces membrane life and performance.

Question 5

Are waterproof membranes slip-resistant for foot traffic?

Accepted Answer

Yes, we offer slip-resistant options including textured membrane surfaces, anti-slip additives, &specialized topcoats. These provide safe traction for pedestrian traffic while maintaining waterproof integrity. Slip resistance can be customized based on expected traffic and safety requirements.

Question 6

What warranty coverage is provided for membrane installations?

Accepted Answer

We provide comprehensive warranties typically ranging from 10-20 years depending on membrane type and application. Warranties cover material defects, installation workmanship, &membrane integrity against water infiltration. Extended warranties are available for premium systems with proper maintenance programs.
